Question

when a substance is heated its density............ ​

Answer 1

Answer:

Higher the volume of the material, lower is its density if its mass is kept constant. Now when temperature of a substance is raised, the volume increases while mass will stay constant in ideal situations. Therefore, with the increase in temperature the density of the substance will decrease

Answer 2

Answer:

• When a substance is heated, its volume increases while its mass remains same, therefore, the density of substance, being the ratio of mass to its volume, decreases with the increase in Temperature.
